Inversion Convergence Tests

These plots demonstrate that the the mean hazard computed from 200 inversion solutions of the same logic-tree branch is equivalent to the hazard computed from the average of the 200 solutions.

The PDF's in this directory are collections of plots showing hazard curves at various CA sites (map). The curves are presented as Annual Frequency of Exceedance vs. ground motion (g). The 2% in 50 year and 10% in 50 year recurrence rates are marked for reference (grey lines).

For these tests, the UCERF3 'reference' branch was used for the inversion [FM3.1, ZENGBB, Shaw09Mod, DsrTap, M5Rate8.7, MMaxOff7.6, SpatSeisU3].

Legend:

DARK BLUE: mean of 200 hazard curves, one from each inversion solution.

LIGHT BLUE: polygon showing minimum and maximum hazard from 200 curves (note: this is generally only visible at a few sites).

BLACK DOTS: hazard from the average of 200 inversion solutions.
